Electrodeionization System is the new method of treatment technology which utilizes electricity, ion exchange membranes and also resin in order  to deionize the water and further separate the dissolved ions  that are basically impurities from water. Being an electrically-driven water treatment technology which makes use of the electricity, ion exchange and also resin so that the ionized species can be removed from the water. As impurities start to leave via the concentrate water system, the build-up formed by them also does not exhaust the resin and henceforth the prolongs resin lifespan. Electrodeionization System is often brought in use post RO for the polishing purpose of the demineralized water in order to obtain low levels of conductivity and silica.
